how to setup a translucent mirror floor with hills ?

Hi,
I think this material is quite challenging to achieve, as I struggled for hours with it.
I’m creating a very specific mood, involving a highly reflective floor, with very sharp reflection of the player. (mirror-like)
I also want it to be translucent. (like a slightly tinted Plexiglas)

I could use a scene capture 2D, placed under the floor and following the main camera, but there are some limitations that I don’t know how to overcome :

  1. if there is a hill, I want my character to get a distorted reflection.

  2. my floor can be used as a floor on both sides : Player A can be on top of the plane, while Player B is upside down walking on the ceiling.
    In this case the scene capture 2D, which would be used for reflections, would see player B top side, and I want it to see only player A from below.

I also tried with just a very high specular, low roughness and high metallic, but the reflections are messy.

Any idea ?

Here is a side view of the situation :

scene capture 2D is not meant for hills, its for flat mirrors. You can distort the uv’s of it with the normals from a texture and the vertex normals itself. The only issues is that your floor will only look correct at the position you place the scene capture 2D.

Only “solution” are:
-Place camera in such a way that the screen space reflection will do it’s job.
-Having a flat floor.
-Not having mirror being super accurate.

Until some voxel or ray tracing comes along these are your best options.

which won’t come anytime soon
